In Australia there's only really one brand of pellets, Vetafarm, so we're not spoiled for choice.
It seems to be more specialized for specific parrots then the American varieties.
For example I have a conure so I buy the South American Mix which was made for macaws, amazons and conures. They even go so far as to say it should be fed as a total diet - fruits and vegetables are optional. "Other supplements are not required." because they add stuff like "Vitamins – A, D, E, K, B1, B2, B3, B6, B12, Minerals – Magnesium, Potassium, Iron, Zinc, Sodium, Manganese, Calcium, Phosphorous, vegetable oils and Amino Acids".
(doesn't stop me sharing my dinner with him)
I may have one brand to choose from, but if its good enough for the Sydney Zoo, its good enough for me.

I saw a video on Youtube of someone tasting 3 kinds of parrot pellets, so I decided to taste the ones I feed Birdy because I didn't want him living off something that tastes terrible. They're actually not bad at all!

Has anyone else tried doing this?
